# Running OpenClaw.app with a Remote Gateway
OpenClaw.app reaches a remote Gateway over an SSH tunnel: an SSH `LocalForward` maps a local port to the Gateway WebSocket port on the remote host.

## Setup
1. Add an SSH config entry with `LocalForward 18789 127.0.0.1:18789` (see [Remote Access](/gateway/remote#macos-persistent-ssh-tunnel-via-launchagent) for the full config block).
2. Copy your SSH key to the remote host with `ssh-copy-id`.
3. Set `gateway.remote.token` (or `gateway.remote.password`) via `openclaw config set gateway.remote.token ""`.
4. Start the tunnel: `ssh -N remote-gateway &`.
5. Quit and reopen OpenClaw.app.
For a tunnel that survives reboots and reconnects automatically, use the LaunchAgent setup on the [Remote Access](/gateway/remote#macos-persistent-ssh-tunnel-via-launchagent) page instead of a manual `ssh -N`.
## How it works
| Component | What it does |
| ------------------------------------ | ------------------------------------------------------------- |
| `LocalForward 18789 127.0.0.1:18789` | Forwards local port 18789 to remote port 18789 |
| `ssh -N` | SSH without executing remote commands (port forwarding only) |
| `KeepAlive` | Restarts the tunnel automatically if it crashes (LaunchAgent) |
| `RunAtLoad` | Starts the tunnel when the LaunchAgent loads (LaunchAgent) |
OpenClaw.app connects to `ws://127.0.0.1:18789` on the client. The tunnel forwards that connection to port 18789 on the remote host running the Gateway.
